Abstract
The choice of breed used in the farm depends on the goals pursued by the owner, and the efficiency of animal use. Not only obtaining high productivity is now a priority, but also the efficiency of using animals, their reproducibility and quality of cattle. To assess the prospects for the use of Ayrshire cattle in the Murmansk region, a comparative analysis was carried out of animals of this breed with Holstein-Kholmogory breed in one of the farms - Polar Star LLC. The estimate of the milk yield showed that Ayrshire breed animals are slightly inferior before Holstein-Kholmogory, but despite this they are able to achieve a high level of productivity - 9-10 thousand kg of milk. They are superior in milk quality composition of the Holstein-Kholmogory, even despite its high productivity. The milk fat content of Ayrshire cows is 4-4.2%. Ayrshire cows have a shorter service period and lactation duration, which has a positive effect on the herd reproduction rate. The study of genealogical groups allowed us to identify the best in reproductive qualities - the line Yuttero Romeo. A similar analysis was carried out among families. The one fairly numerous family of Ayrshire breed (family Lomka 1076) was among the best. Evaluation of bulls by fertilizingcapacity did not allow unequivocally distinguish representatives of the Ayrshire breed as leaders. Both the Ayrshire and Holstein bulls had different reproductive abilities. Thus, the analysis made it possible to identify good prospects when using the Ayrshire breed in the conditions of the Far North and them high competitiveness. However, it is necessary to continue to improve the breed, especially in the direction of improving reproductive abilities.
